Bisoprolol transdermal patch improves orthostatic hypotension in patients with chronic heart failure and hypertension.

β blockers (BBs) play an important role in heart failure (HF) treatment. However, orthostatic hypotension (OH) is sometimes caused by BBs. The bisoprolol transdermal patch works more slowly and is long acting compared with the bisoprolol fumarate tablet. The risk of OH may be reduced by using the bisoprolol transdermal patch. We evaluated 57 consecutive patients who were taking the bisoprolol fumarate tablet for chronic HF with hypertension from November 2016 to September 2017. We switched the patients to the bisoprolol transdermal patch. Because 12 of 57 subjects could not continue using the bisoprolol transdermal patch, we analyzed the remaining 45 patients. We investigated BP, blood tests, and changes in BP from supine to standing positions before and after 6 months of switching from tablet to patch. OH was diagnosed by observing a systolic/diastolic BP drop of at least 20/10 mmHg or an absolute systolic BP (sBP) of <90 mmHg from the standing position. No significant changes were observed in the BP and BPs from supine to standing positions, whereas log brain natriuretic peptide was significantly reduced after switching from patch to tablet (2.102 to 2.070pg/dl,
